I think you're unjustly attacking solo businesses by saying that we're a bunch of geeks afraid to talk to people.
You can definitely scale in headcount and try to build a Freshbooks or Harvest and have millions a year in revenue, or build a business that requires touchy sales and commission payments. Or you can be like Amy and Thomas with Freckle and have a very minimal organization that nets a few hundred thousand.
It's a lifestyle choice, and neither approach is the "right" one.
